Refractory Zirconia Tundish Nozzle
High-purity zirconium material: Enhances high-temperature resistance and resistance to molten steel erosion
Excellent anti-clogging performance: Reduces slag adhesion and ensures stable continuous casting
Extended service life: Reduces replacement frequency and minimizes downtime losses
High-density structure: Effectively prevents penetration and erosion
Customization available: Tailored to meet the equipment and process requirements of different steel mills
Product Structure and Performance Specifications
The nozzle of the refractory zirconia ladle is manufactured using a high-density sintering process, ensuring structural stability even under the erosion of high-temperature molten steel.
Its internal channels have been optimally designed to reduce turbulence in the molten steel, thereby:
- Reducing the adhesion of inclusions
- Improving the purity of the molten steel
- Reducing the risk of clogging
It is particularly suitable for continuous casting lines with stringent requirements for molten steel quality.
